Ipsos MORI gave the Tories a 3% lead on 11th October.
Sunday morning update: "Unlike YouGov’s poll published on Friday (although actually conducted slightly later than this one) the poll suggests that Labour have begun to recover slightly from their position earlier this month. With the present erractic position in the polls though it is hard to say for sure – we will have another two polls in the week from ICM and ComRes which may shed some light, but it looks as though we can conclude little other than that the two main parties are close to one another in the high thirties and low fourties, with the leaderless Liberal Democrats languishing in the low teens. All depends on what happens when they get a new leader – whether they recover support and, if so, at whose expense?" – from UK Polling Report.
